+
+## Simple unit tests
+
+This framework is as unit testing for individual javascript functions.
+
+## Adding new test
+
+Follow the existing structure, always returning the number of errors and tests.
+
+Keep in mind, test the simple cases like:
+* Working cases
+* No parameters when exepecting some
+* Incorrect data types
+* Empty, null, undefined values...
